Index LookUp Table
Description
The Index Lookup Table block lets you access values stored in a lookup table (LUT). They're accessible through a table index input pin.
Usage
click Table to open the Table Editor window. There are two ways to enter values:
- Enter them directly and use Save table value.
- Use Load table value to load data from a file.
The first option lets you enter maximum value(s).
Description: For this algorithm, the input is the index value into the LUT. The module expect the index to be in integer format 32.0. Zero (0) will index the first value in the table.
